JOHN E. MCCRAY, OF HAUGI-IVILLE, INDIANA.

LOADING DEVICE.

To all whom it may concern:

Be it known that I, JOHN E. MOCRAY, of Haughville, county of Marion, andState of Indiana, have invented a certain new and useful Loading Device;and I do hereby cleclare that the following is a full, clear and exactdescription thereof, reference being had to the accompanying drawings,in which like letters refer to like parts.

The object of this invention is to improve the construction andoperation of that class of excavating machines which simultaneouslyexcavates the material, elevates the same and loads it into a wagonwhereby it is hauled away.

One feature of this invention consists in combining with such travelingexcavator, a transversely revolving wheel for elevating the dirt anddischarging it upon a conveyer or other means for receiving it. To thisend said transversely mounted elevating wheel is open on its front sideand is annular with buckets on the internal periphery of the wheel, anda conveyer extends forwardly from a point within the upper part of thewheel in a position to receive the dirt as 1t drops from the upper partof the wheel. This conveyer deposits the dirt in a wagon hitched to theforward end of the excavating machine and means is mounted on the frameof the machine for vertically adjusting said conveyer.

Another feature of the invention consists in the means shown forcharging the wheel with dirt. There is a plow or scraper that separatesthe dirt from the ground and which moves in advance of the wheel and, ifit be far enough in advance, the dirtis ,moved from the plow or scraperrearwardly to the wheel and discharged within the same.

Another feature of the invention consists in providing a vehicleconnected to the rear of the excavating machine to which a team may behitched for pushing the machine forward, and this pushing meanscooperates with a pulling means; namely, a wagon in advance of themachine and connected therewith. Therefore one team pulls the wagon andhelps pull the machine while another team pushes the machine.

Another feature of the invention consists in means for automaticallyhitching the machine to the wagon and manually operated means forreleasing the same.

The full nature of the invention will be understood from theaccompanying draw- Specification of Letters Patent.

ings and the following description and claims.

In the drawings Figure l is a side elevation of the excavatingapparatus. Fig. 2 is a plan view thereof. Fig. 3 is a central verticalsection through the excavating machine and the rear half of the wagon,with the machine hitched to the wagon in condition for operation. Fig. 4is a side elevation of the frame of the machine and the rear half of thewagon, the latter being in dotted lines, showing the parts after themachine had been disengaged from the wagon. Fig. 5 is a verticaltransverse section on the line 5-5 of Fig. 1. Fig. 6 is a perspectiveview of the conveyer supporting means. Fig. 7 is a vertical transversesection through a part of said means. Fig. 8 is a detailed view of thespring support for the connection between the wagon and machine. Fig. 9is a perspective view of the forward part of the means for picking upthe dirt from the ground and conveying it to the elevating wheel.

In detail the drawings herein show an excavating machine, a wagon 20 infront thereof to receive the dirt and haul it away, and a push-cart 21at the rear thereof to assist in propelling the machine. The pushcartshown is adapted for four horses and the forward end of the tongue isremovably connected with the rear part of the frame 22 of the excavatingmachine, whereby the power exercised by the team on the push cart willbe applied to the machine for pushing the same forwardly. The teamhitched to the wagon also assists in advancing the excavating machine.There is a connecting bar 23 pivoted at its rear end at 24 to theforward end of the frame 22 of the machine. Said connecting bar has anotch 25 near its forward end adapted to engage the rear axle 26 of thewagon so that the wagon will pull the machine. The forward end of theconnecting bar 23 is beveled at 27 on its upper side so it will slipunder the axle of the wagon when the wagon is backed into place forloading. The connecting bar is held in engaging position by a cable 28extending from the upper side of said bar over the shaft 29 mounted onthe stands 30 and about wheel 31 to a hand lever 32 at the rear part ofthe machine near the seat 33. A notched segment 34: locks the lever 32in position. A yielding spring construction 35 is imposed between theends of said cable 28 so that lOii said cable forms a yielding supportfor the bar 23. After the wagon is backed into place for loading thelever 32 is drawn rearwardly which couples the wagon to the machine asshown in Fig. 3. After the wagon has been loaded the cable 28 isrelaxed, thus disengaging the connection 23 from the wagon. The frame 22is carried by a pair of wheels 40 and the axle 41 passes through thestands or bearings 42. Between said traction wheels 40 an elevatingwheel 43 is mounted transversely of the machine, as seen in Fig. 5. Aspindle 44 is mounted at one end in the rearward extension 45 of theupper end of the post 46 and at the other end in the bearing post 47.The elevating wheel is annular with its forward side open and its rearside closed. On its rear side it has an annular rack 48 which is engagedby a pinion 49 on the shaft 50. This shaft is driven by a sprocket chain51 running over a sprocket wheel on the outer end of the shaft 50 andthe sprocket wheel 53 on the axle 41. The elevating wheel 43 has in itsinternal periphery buckets 55 arranged so as to hold the dirt depositedat the bottom of the wheel and carry the same to the top of the wheelwhere it will be discharged by gravity.

The elevating wheel is charged with dirt by the following means: A scoopor a plow 56 is drawn by rods 57 extending forwardly and upwardly andconnecting with the cranks 58 on the rod 59 to which a long hand lever60 is secured, whereby said scoop or plow can be elevated or lowered.Vheels 62 are mounted at the rear end of the said scoop or plow so as torun on the ground, and the dirt is carried from the plow 56 rearwardlyto the wheel 43 by the conveyer 63 on the frame 64, that at its forwardend is supported by the plow 56 and at its rearward end by the arm 64extending downwardly from the frame 23, see Fig. 5. This conveyer isdriven by a sprocket chain 51 running over the shaft 66, which shaft ismounted in the bearing posts, 46, 67, and 68. Said shaft 66 is driven bya gear 69 thereon meshing with the gear wheel 70 on the axle 41. Theconveyer 63 projects at its rear end into the lower part of wheel 43 soas to discharge the dirt thereon, see Fig. 3. The wheel 43 dischargesthe dirt on a long forwardly extending horizontal conveyer 7 5 operatingon a frame 7 6 mounted at its rear end on the rod 7 7 in the stands 78and 79 extending up from the stands 46 and 67, see Fig. 5. Said conveyerframe is supported substantially by toggles 80 that extend up from eachside of the frame 24 and are contracted or expanded for elevating orlowering the conveyer by cables 81 surrounding the shaft 29 which isactuated by the handle 84, see Fig. 7, and locked by the key 85 passingthrough a hole in the flange 86 connected with the handle and a hole 87in the stand 30. The conveyer is actuated by the sprocket chain 90running from the sprocket wheel 91 on the axle 41 to a sprocket wheel onthe drum 92 at the rear end of the conveyer frame. The rear end of theconveyer projects within the upper part of the wheel so the dirt will bedischarged thereon and an-annular tapering guard plate 93 is secured tothe inner surface of the rear wall of the wheel 43 and projects beyondand above the rear end of the conveyer 7 5. All dirt that falls on theplate 93 rolls on the conveyer 75, and the conveyer discharges the dirt94 into the wagon.

The forward end of the excavating machine is guided by the followingmeans: A

pair of wheels 100 is mounted on the ends of the axle 101 that iscentrally mounted in the lower part of the bearing 102 extending downfrom the frame 23 so that the axle 101 is oscillatory. It is oscillatedfor steering the machine by cables 103 extending therefrom rearwardly toa drum 104 mounted in brackets 105. Said drum 104 is actuated by wormgears 105 and 106, the former on a drum and the latter on a verticalsteering rod 107 mounted on the bracket 108 and having a steering wheel109 on its upper end. hen the wheel 109 is turned in either direction itwill correspondingly actuate the axle-101 and steer the machine.

hat I claim as my invention and desire to secure by Letters Patent is:

1. An excavating machine including a vehicle having a frame and tractionwheels, an elevating wheel mounted between the traction wheelstransversely of the vehicle, means for taking up the material from theground and depositing the same on the wheel, a conveyer extendinglongitudinally of the vehicle, means on the frame for supporting theconveyer so that the rear end thereof will receive the material elevatedby the wheel, and a receptacle attached to said frameand located underthe forward end of said conveyer for receiving the material therefrom.

2. The combination of a wagon having a rear axle, an excavating machine,and a spring elevated connection with the forward part of the excavatingmachine having a notch in its upper side to engage said axle, wherebythe wagon will draw the excavating machine.
